Hi all,

i have a question about gaussian_kde method.

I use that method in this way:



kernel = stats.kde.gaussian_kde(values)



I think as write in the documentation "If None (default), ‘scott’ is used."

the scott method is used as default.

My question is: Is it possible to get the bandwidth  value used ? I would like

to show this value in my script.



Thanks



Francesco
